You may have seen the popular television quiz for teenagers on which this game is based. In it, two contestants try to answer general knowledge questions, attempting to cross the board from one side to the other.
Instructions The board on which our game is played contains twenty-five squares in the configuration of a five by five grid, as shown below: A F B T C
Z C W V L
R S G K X
R E P J I
M O N H UIn each of the squares is a different letter, which is the initial letter of the answer to a question which is posed when a player selects that square. When the game is played the first person to press his button has the right to answer, and if he answers the question correctly the square is filled with his colour. If he is wrong the second player has an attempt, but if neither player answers correctly, a square must be reselected.The game ends when one player has a complete line across the board or all the squares are occupied. The first requirement on executing this program is to enter the database, which takes the usual amount of time. When the internal buffering has finished, the blockbuster board is displayed. The names of the two players are entered, with player one trying to connect left to right with yellow squares and player two working from top to bottom in blue. After these directions are given a coin is thrown inside the computer's memory to decide who is to have the initial choice of square. When this has been selected the game begins. You are warned that the question is imminent by being told to place your fingers on your buzzers. Player one's buzzer is the 'KEY-1' on the top row of the keyboard; player two's is the 'KEY-2' of the numeric keypad on the right-hand side of the computer. When the question is displayed the first player to press his buzzer wins the right to answer the question (when the buzzer is pressed it should not be held down, as this can cause problems when typing in the answer). The person who types in the correct answer within the time limit will shade the square in his colour. For a player to win he must create a pathway from one side of the board to the other, but diagonal steps are not permitted. Hence for player one, the path shown on the right below would not be a winning line, but the one on the left would. |
